Compared to the stem-guided series, cage guided control valves feature larger trim sizes (available in 2\" to 10\" end connections) for higher valve coefficients (Cv). Cage guided control valves can be equipped with an optional electric drive or operated with compressed air to meet zero-emission requirements.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:image {\"align\":\"center\",\"id\":26426,\"width\":512,\"height\":384,\"sizeSlug\":\"large\",\"linkDestination\":\"none\"} -->\r\n<figure class=\"wp-block-image aligncenter size-large is-resized\"><img class=\"wp-image-26426\" src=\"https:\/\/zecovalve.com\/wp-content\/uploads\/2022\/08\/Control-Valve-0-1024x768.jpg\" alt=\"\" width=\"512\" height=\"384\" \/><\/figure>\r\n<!-- \/wp:image -->\r\n\r\n<!-- wp:heading -->\r\n<h2>Structure of Cage Guided Globe Valve<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nCage-guided globe valves are available with both balanced and unbalanced plugs.
